2013 TH172 is a large asteroid whose orbit extends beyond the orbit of Neptune. NASA JPL has not classified 2013 TH172 as potentially hazardous because its orbit does not bring it close to Earth.
2013 TH172 orbits the sun every 102,000 days (279.26 years), coming as close as 31.40 AU and reaching as far as 53.84 AU from the sun. Based on its brightness and the way it reflects light, 2013 TH172 is probably between 80.270 to 179.490 kilometers in diameter, making it larger than 99% of asteroids, very roughly comparable in size to the U.S. state of Delaware.
2013 TH172's orbit is 30.40 AU from Earth's orbit at its closest point. This means that there is an extremely wide berth between this asteroid and Earth at all times.
Orbital simulations conducted by NASA JPL's CNEOS do not show any close approaches to Earth.
2013 TH172's orbit is determined by observations dating back to Oct. 3, 2013. It was last officially observed on Sept. 18, 2017. The IAU Minor Planet Center records 21 observations used to determine its orbit.
